Dark-rey DPS club parses, Assassin deception - In need of help

Last August (around 20.) I broke my 10K DPS http://parsely.io/parser/view/312319/0 After that I had to take a break from gaming and just returned to the game. The gear I used was 248 full aug. - 1E + 3A for accuracy - 5E + 5A for alacrity - 4E + 6A for critical - critical crystals and accuracy stim

Now that I returned to the game I barely managed 9K DPS with the same gear and some of the aug uppgraded to 236. WTF?
